EMBROIDERY-HOOP.

SPECIFICATION forming part of Letters Patent N 0. 679,510, dated July30, 1901. Application filed September 22, 1900. Serial No. 30.839. N0 ml- To (0Z5 whom, it may concern.-

Be it known that I, JOHN H. POST, a citizen of the United States, and aresident of Andover, in the county of Tolland and State of Connecticut,have invented certain new and useful Improvements in Embroidery-Hoops,of which the following is a full, clear, and exact description,wherebyany one skilled in the art can make and use the same.

My invention relates to the class of devices used for holding a fabric,as of silk, linen, or the like, while it is being embroidered; and theobject of the improvement is to produce an embroidery-hoop with asimple, compact, and effective means for holding the severed section ofthe hoop with its ends in alinement and the two sections compressed uponthe fabric.

'Referring to the drawings, Figure 1 is a plan view of the improvedhoop. Fig. 2 is a detail view in elevation, on enlarged scale, showingthe meeting ends of the outer hoop and the compound spring.

In the accompanying drawings the letter a denotes the inner section ofthe embroidery-hoop, and Z) the outer section, the latter being dividedby a transverse opening extending in an indirect line across the hoop,so as to form in one end what may be termed a recess (Z and on the othera projection e, so that the ends of the hoop are engaged in such manneras to cause them both to move together when an attempt is made to slidethe outer hoop transversely of the surface of the inner hoop eitherupward or downward.

The ends of the hoop-section b are drawn toward each other by means of acompound spring f, which is of peculiar construction and is secured atits opposite ends to fastening-points g h, respectively, on oppositesides of the opening 0 in the hoop. This spring is formed, preferably,of spring-wire bent into a series of loops f, which extend alternatelyin opposite directions across a line drawn between the ends of thespring and forming its central line. In addition to the bends describedthe spring is also bent flatwise, so as to conform substantially to theouter surface of the hoop. WVhen this spring is fastened in place bymeans of the studs or rivets, it is put under a slight tension, so thatit will draw the opposite ends of the hoop toward each other.

When a piece of fabric is placed upon the inner hoop and the outersection is then exerts its force, first, to resist the separation of theends, which tends to flatten the spring, and, secondly, by theresistance offered by the bends to any attempt to change the shape bythe pull in an outwardly direction upon the opposite ends.

WVhat I claim as my invention, and desire to secure by Letters Patent,is

1. In combination in an embroidery-hoop, an inner section, an outersection having a cut extending in an indirect line across the hoop fromedge to edge and providing separated interlocked ends, and a compoundspring extending across the cut and attached at opposite ends to therespective ends of the hoop-section.

2. In combination in an embroidery-hoop, an inner section, an outersection having a cut extending in an indirect line across the hoop fromedge to edge and providing separated interlocked ends, and a compoundspring of wire bent to conform to the outer surface of the hoop-sectionand also in loops which extend alternately in opposite directions acrossthe central line of the spring,

and means for attaching the opposite ends of the spring to therespective ends of the outer section of the hoop.

3. In combination in an embroidery-hoop, an inner section, an outersection having a cut extending in an indirect line across the hoop fromedge to edge and providing separated interlocked ends, and means foryieldingly holding said ends in engagement.

4. In combination in an embroidery-hoop, an inner section, an outersection having a V-shaped cut separating the ends and providinginterlocking parts arranged to prevent independent lateral movement ofthe ends, and means for yieldingly holding said ends in engagement.
